Abstract

Abstract The 13C NMR chemical shifts of 3H-phenoxazin-3-one (1) and eighteen of its derivatives are reported. The chemical shifts of 1 can be explained in terms of a successive polarization of the π-conjugated framework by an electron-withdrawing carbonyl group and a π-donating ether oxygen. The pri...
